20.500.12556/RUL-176366 Design and implementation of a circular remanufacturing production line Zasnova in izvedba krožne proizvodne linije za predelavo The growing concern over resource scarcity and environmental damage has exposed the limitations of linear production models “take-make-dispose”. On this basis, circular economy and remanufacturing, provide effective solutions by extending product lifecycle, value preservation, and reducing the energy and materials consumption. This thesis presents the design and implementation of a pilot remanufacturing production line, with the objective of demonstrating its viability and evaluating its performance. A hydro turbine was selected as case study, and the remanufacturing stages – disassembly, diagnostic, cleaning, repairing, kitting, reassembly and quality control – were physically implemented, simulated and tested. Lean manufacturing principles were applied to improve workflow, while Industry 4.0 technologies were integrated to improve accuracy, ergonomics, quality, data management and decision-making. The experiments of remanufacturing confirmed the technical feasibility of circular remanufacturing chains and demonstrated their potential advantages over linear models. Measured indicators such as value-added time, Material Circularity Index, and carbon footprint revealed improvements in productivity, quality, and sustainability. Overall, the thesis contributes to bringing together theory and practice in circular economy by offering a replicable framework for research and education, supporting the ecological transition towards more sustainable and digitalized manufacturing systems. Naraščajoča zaskrbljenost zaradi pomanjkanja virov in okoljske škode je razkrila omejitve linearnih proizvodnih modelov »vzemi-izdelaj-zavrzi«. Na tej podlagi krožno gospodarstvo in predelava zagotavljata učinkovite rešitve s podaljševanjem življenjskega cikla izdelkov, ohranjanjem vrednosti ter zmanjšanjem porabe energije in materialov. Ta diplomska naloga predstavlja zasnovo in izvedbo krožne proizvodne linije za predelavo s ciljem prikazati njeno izvedljivost in oceniti njeno delovanje. Kot študija primera je bila izbrana hidroturbina, faze predelave – demontaža, diagnostika, čiščenje, popravilo, kompletiranje, ponovna montaža in nadzor kakovosti – pa so bile fizično izvedene, simulirane in preizkušene. Za izboljšanje poteka dela so bila uporabljena načela vitke proizvodnje, tehnologije Industrije 4.0 pa so bile integrirane za izboljšanje natančnosti, ergonomije, kakovosti, upravljanja podatkov in odločanja. Poskusi predelave so potrdili tehnično izvedljivost krožnih verig predelave in pokazali njihove potencialne prednosti pred linearnimi modeli. Izmerjeni kazalniki, kot so čas dodane vrednosti, indeks krožnosti materialov in ogljični odtis, so pokazali izboljšave v produktivnosti, kakovosti in trajnosti. Na splošno diplomsko delo prispeva k povezovanju teorije in prakse v krožnem gospodarstvu, saj ponuja ponovljiv okvir za raziskave in izobraževanje ter podpira ekološki prehod k bolj trajnostnim in digitaliziranim proizvodnim sistemom. remanufacturing circular economy industry 4.0 sustainable manufacturing production line ponovna izdelava krožno gospodarstvo industrija 4.0 trajnostna proizvodnja proizvodna linija true false false Angleški jezik Slovenski jezik Magistrsko delo/naloga 2025-11-28 08:30:41 2025-11-28 08:30:46 2025-12-20 04:06:56 0000-00-00 00:00:00 2025 0 0 XXV, 77 str. 2025 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 658.51:502:621.224-027.33(043.2) 279823 261620739 45151.pdf 45151.pdf 1 9041BE2A1632FBDF830D62F0F5165DB2 bf9da4dcf49c6c2655e1a64ddffb1542a401e775a60f66cb50e6f00fceb3eaf5 c993f38b-cc2b-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=222671 Fakulteta za strojništvo 0 0 0
